正常和妊高征胎儿静脉导管分流率检测的临床应用

Clinical application of the detection of fetal venous catheter shunt rate in normal and pregnancy induced hypertension

目的:探讨超声检测正常和妊高征胎儿的静脉导管分流率及其意义。方法:收治妊高征胎儿50例为观察组,同期正常胎儿50例为对照组,观察静脉导管血流量、静脉导管峡部内径、奇静脉血流量、静脉导管分流率。结果:与对照组相比,随着孕妇妊高征严重程度的上升,胎儿静脉导管血流量、静脉导管峡部内径以及静脉导管分流率也逐渐随之增加(P均<0.05),而脐静脉血流量逐渐降低(P<0.05)。结论:超声检测正常和妊高征胎儿静脉导管分流率,可以判断其严重程度,具有重要意义。

Objective:To investigate the ultrasound examination of the normal and pregnancy induced hypertension in the fetal venous catheter shunt rate and its significance.Methods:50 pregnancy induced hypertension were selected as the observation group,50 normal fetuses were selected as the control group at the same period,we observed the blood flow of venous catheter, venous catheter,isthmus diameter azygos vein blood flow,venous shunt rate of them.Results:Compared with the control group,with the increase of the severity of pregnancy induced hypertension,the fetal ductus venosus blood flow,vein catheter isthmus diameter and venous catheter shunt rate was increased(all P<0.05),and umbilical venous blood flow decreased gradually(P<0.05). Conclusion:Ultrasound examination of the rate of fetal venous catheterization in normal and pregnancy induced hypertension,it can judge its severity,and has important significance.
